In this interview from Phi Moments at Google Cloud Next, Harshini Infanta, associate practice lead of agentic enterprise intelligence at Quantiphi, joins Vishal Gupta, chief techco transformation and procurement officer of Indosat Ooredoo Hutchison, to talk with theCUBE's Rebecca Knight about reimagining a 100-million-subscriber telecom as an AI-first organization anchored by a sovereign AI platform built to serve every corner of Indonesia. Gupta explains how Indosat's mission to empower every Indonesian drove its pivot from traditional telco to techco, using AI as a democratizing force across an archipelago of 17,000 islands. At the center of that vision is Sahabat-AI — not just a large language model, but a sovereign ecosystem designed to preserve the cultural and linguistic nuances of Bahasa and guard against what Gupta calls "digital colonization." Infanta describes Quantiphi's role as co-architect alongside Google Cloud, positioning the company as an industrializer that makes transformative technology invisible — infrastructure so embedded it simply works. The conversation also explores the organizational redesign required to operate as a truly AI-first enterprise. With agent workers projected to outnumber human workers at Indosat within a few years, Gupta details how the company built change management from the top down — running quarterly two-day immersion sessions first with 13 CXOs, then expanding to 100 senior leaders, framing agentic AI as empowerment rather than displacement. Infanta outlines how Quantiphi's platform-led, modular approach — now accelerated by Gemini Enterprise — ensures deployments scale beyond one-time initiatives. She introduces the principle of adoption-led engineering: building with the end user in mind from day zero, so solutions earn trust before they scale. Both guests close with advice for senior leaders navigating AI-first transformation. Infanta emphasizes collaborative ownership and obsessive ROI measurement, while Gupta distills the challenge into three principles — speed as strategy, organizational metabolism as the true constraint and trust as the scarcest resource in any agentic environment. From democratizing AI across 17,000 islands to building a replicable blueprint for sovereign, human-centered transformation, the discussion charts how bold ambition and engineering discipline can converge at scale.
